Aiming the AGM-123 is impossible to aim in SIM and using it at its max range of 20km is next to impossible as well.
Using CCRP or CCIP does nothing to help unless you attack from an 80 to 90 degrees down. The impact point is so far below you on the HUD you can never get it in the fame in an attack run unless you want to die to an SPAA,
Aiming or knowing when to release the AGM-123 is down luck, unlike any other plane ATGM or Bombs in the game you have to calculate Air craft pitch, Speed, Height, and Weather, this gives the player attacking ground targets an unfair playing field the same fairness as all other Laser-guided bombs should be implemented here for the AGM-123
